Infrared monitoring warner of abrasion of balance disc of multi-stage pump and infrared monitoring method thereof

Abstract

The invention discloses an infrared monitoring warner of abrasion of a balance disc of a multi-stage pump and an infrared monitoring method thereof. The infrared monitoring warner comprises a bracket arranged at the tail end of a non-motor coupling shaft end of the spindle of the multi-stage pump; a plurality of infrared emission pipes are sequentially arranged on one side of the bracket, infrared receiving pipes matched with the infrared emission pipe in a one-to-one manner are arranged on the other side, each infrared emission pipe and the infrared receiving pipe that are matched with each other form a monitoring element, the infrared emission pipes are connected to the two ends of an input power source in parallel, and the infrared receiving pipes are eclectically connected with a displacement signal light and then is connected to the two ends of the input power source in parallel. The infrared monitoring warner can display the abrasion loss of the balance disc of the multi-stage pump in real time without stopping the pump and removing the pump body, thereby avoiding the miss judgment or misjudgement to the abrasion condition of the balance disc due to experience; the infrared monitoring element has simple structure, small volume, practicability and higher detection precision and reliability.

Description

technical field [0001] The invention relates to an infrared monitoring and alarm device for multistage pump balance disk wear and an infrared monitoring method thereof. Background technique [0002] At present, the known multi-stage pump balance plate is a device for balancing the axial water thrust of the multi-stage pump by utilizing the change of gap flow. However, due to the influence of the fluid medium, the balance plate is often worn, making it lose the effect of balancing the axial water thrust. During the operation of multi-stage pumps, management personnel should know the wear of the balance plate in real time, and repair and replace it in time to ensure that the balance plate can work normally. Because the balance plate is installed in the pump body, it is difficult to directly observe its wear and tear. Generally, the wear of the balance plate of a multi-stage pump is judged by the work experience of the operation management personnel, and often there will be mi...

Problems solved by technology

Because the balance plate is installed in the pump body, it is difficult to directly observe its wear and tear. Generally, the wear of the balance plate of a multi-stage pump is judged by the work experience of the operation management personnel, and often there will be missed judgments or wrong judgments. The safety production brings hidden dangers; if the pump is regularly stopped to disassemble the pump body for observation, it is not economical and affects the production of the enterprise at the same time
